Struct EnvStep 

pub struct EnvStep {
    pub entry: EnvEntry,
    pub origin: Origin,
    pub applied: bool,
    pub replaced_by: Option<Origin>,
    pub removes: Option<Origin>,
}

What one env entry of a Resolution does in a process.

Fields

entry: EnvEntry

The entry: the variable and the value it sets, or none to remove it.

origin: Origin

The rule that set it.

applied: bool

False for a default whose variable the process already had, which it leaves alone.

replaced_by: Option<Origin>

The origin of a later entry for the same variable that applies, which replaces what this one did: the variable ends up with that entry’s value.

removes: Option<Origin>

For an entry that removes the variable, the origin of the earlier entry for it that applied and set a value, which the removal undoes.
